Same thing happened to me on a steel frame. Qr failed during a sprint and bent out the seat and chain stays exactly like that. Luckily I stayed up and skidded to a halt (shredded right through the tire). Mechanic was able to bend it back into place but I didn't feel comfortable riding it after that.

that picture is very telling. just like the OP's situation.i gotta say that aftermarket, exposed-cam QRs are at least partly to blame. they simply dont clamp as hard for a given effort. and the pivot lube dries out and it gets ten times worse. a drop of lube goes a long way with those...

What would you think of the security (not convenience) of QRs that install with an hex wrench? I've seen some very light-weight (30g-40g) QRs that install this way.

the 30-40g ones are titanium, and you have to be really careful with them. They tend to bind up a bit, and you can shear the heads off of them if not careful. There's a very fine line between tight enough, and too tight. I ended up snapping the head off one of mine trying to unscrew it, and stripping the hex bolt out of the other one in a hurry. Not the sort of reliability I was looking for in a skewer

So now I run ~70g steel ones, and am pretty happy with them (halo - they were ~$20). Great clamping force. And since I carry a 5mm hex wrench with me all the time anyways, not a huge deal. Granted flat repairs take a little bit longer, but I'm willing to make that sacrifice.
